Nearly 100 members of the U.S. Congress have now taken a stand for equality by participating in the No H8 campaign by photographer Adam Bouska. No H8's third installment of "No H8 on the Hill," which released photos of 67 members of Congress today, includes several out gay and bisexual congresspeople, the campaign's first senators, and the first Republican to call for LGBT equality.

"The growth of No H8 on the Hill in so short a time — from ten participating members of Congress to 98 members of Congress and two U.S. senators — proves that hearts and minds are changing across the country," said No H8 Cofounders Bouska and Jeff Parshley. "We're on the cusp of marriage equality, and we're proud to have these elected officials sending a strong, clear message of support: No Hate."

New Mexico's Martin Heinrich formally became the first U.S. senator to participate in the campaign, which now also includes Florida representative Ileana Ros-Lehtinen, the first Republican member of Congress to come out in support of marriage equality, also making her the first Republican to pose for the No H8 campaign.

The latest batch of "No H8 on the Hill" photos also features a striking image from Arizona representative Kyrsten Sinema, the first openly bisexual person elected to Congress, as well as California representative Mark Takano, the first openly gay person of color elected to Congress.

“Our nation is based on the principle of equality. That is what this is all about," said Florida representative Ileana Ros-Lehtinen, a Republican.
